The potted up amaryllis, which can be bought ready-made, is getting more and more popular. For growers specialized in this sort, it is very important to have disposal of bulbs, which develop quickly and show both buds in a short time.
The amaryllis is marketed as an one- or a two pitted plant. Therefore it is nice if you can quickly state if you are dealing with an one- or a two-pitted plant.

To be able to have disposal of “quick growing bulbs” it is important to pay attention to long prepared bulbs and “quick varieties”.
Bulbs from the Southern Hemisphere have often been dug up 2 or 3 months earlier than the Dutch ones. So on the moment they are being planted they have had a longer preparation period behind them. Bulbs from the Mediterranean Sea area have on the average been dug up one month earlier and therefore they have got a lead as far as the pot cultivation is concerned.

After the preparation period, during which the bulbs are being stored at 13°C and under a relative humidity of 80 percent, they are being heated by 25°C – 30°C. This process can be carried out in the cells, while the trays with bulbs remain piled up.
The first couple of days after the start of the heating process are the most suitable days to carry out the necessary combat against trips and Tarsonemus mites.
Sometimes it is already possible to put quick varieties into pots after a couple of days. The bulbs are being put in pots with a food lacking, non-waterproof, sour till neutral medium and need to have disposal of plenty of water.
The ground and space temperature needs to be 20°C – 25°C. Under lower temperatures “red” can come into being as a result of stagnospera and colletotricum. It is possible to cultivate at a lower temperature, but only if you are watering the bulbs at the bottom. Dependent on the variety you can have buds of ±10cm after 2 or 4 weeks after the heating process. The plant is now ready for sale (this is to say, under the Dutch regulations).

Unfortunately there is not yet a recipe to obtain the ideal proportion between the length of the leaf and the flower. This has got to do with:
